“…In face perception, it has been shown that a chimeric face made from two left half faces from the viewer's perspective is usually judged more similar to the original face compared with that made from two right half faces (Gilbert and Bakan, 1973;Brady, Campbell, and Flaherty, 2005;Figure 4). This left side bias has been argued to be an indicator of RH involvement in face perception (Burt and Perrett, 1997), and may be related to visual expertise.…”

Until the day we can record from multiple neurons in undergraduates, understanding how humans process faces requires an interdisciplinary approach, including building computational models that mimic how the brain processes faces.Using machine learning techniques, we can often build models that perform the same tasks people do, in neurophysiologically plausible ways. These models can then be manipulated and analyzed in ways that people cannot, providing insights that are unavailable from behavioral experiments. For example, as we will see below, our model of perceptual expertise can be "raised" in an environment where its "parents" are cups or cans instead of faces, and the same kind of processing ensues. This demonstrates, at least from our point of view, that there is nothing special about faces as an object class per se; rather, it is what we have to do with them -fine level discrimination of a homogeneous class -that is special.In this chapter, we will delineate two dimensions along which computational models of face (and object) processing may vary, and briefly review three such models (Dailey and Cottrell, 1999;O'Reilly and Munakata, 2000;Riesenhuber and Poggio, 1999). Subsequently, we will focus primarily on the model we are most familiar with (our own!) and how this model has been used to reveal potential mechanisms underlying the neural processing of faces and objects -the development of a specialized face processor, how it could be recruited for other domains, hemispheric lateralization of face processing, facial expression processing, and the development of face discrimination. At the end, we return to the Riesenhuber and Poggio model to describe the elegant way it has been used to predict fMRI data on face processing. The overall strategy of these modeling efforts is

“…Although our facial configuration is more or less symmetrical along the vertical axis, we are more likely to use facial cues contained in the right side of the owners' face (left side of the viewed face from viewer's perspective) to facilitate perceptual judgement of gender, age, identity, expression, likeness and attractiveness (Brady et al 2005;Burt and Perrett 1997;Butler et al 2005;Gilbert and Bakan 1973).…”

Consistent left gaze bias in processing different facial cues

While viewing faces, humans often demonstrate a natural gaze bias towards the left visual field, that is, the right side of the viewee's face is often inspected first and for longer periods. Previous studies have suggested that this gaze asymmetry is part of the gaze pattern associated with face exploration, but its relation with perceptual processing of facial cues is unclear. In this study we recorded participants' saccadic eye movements while exploring face images under different task instructions (free-viewing, judging familiarity and judging facial expression). We observed a consistent left gaze bias in face viewing irrespective of task demands. The probability of the first fixation and the proportion of overall fixations directed at the left hemiface were indistinguishable across different task instructions or across different facial expressions. It seems that the left gaze bias is an automatic reflection of hemispheric lateralisation in face processing, and is not necessarily correlated with the perceptual processing of a specific type of facial information.

“…Behavioral evidence has shown that left-right reversal differentially influences the perceived familiarity of one's own face and that of another person's face (Brady, Campbell, & Flaherty, 2005;Brédart, 2003;Mita et al, 1977;Rhodes, 1986). Whereas mirror reversed self faces are perceived as more familiar than non mirror-reversed ones, the opposite is true for other (familiar) persons' faces.…”

“…These findings show that the magnitude of the size overestimation bias of mirror reflections decreases after mirror image interactions (Lawson & Bertamini, 2006), but also that the effect of mirror-reversal is not abolished by this interaction and likely arises due to different mechanisms. The role of mirror-reversal for highly familiar faces has previously been addressed (Brady, Campbell, & Flaherty, 2004;Brady et al, 2005;Brédart, 2003;Mita et al, 1977;Rhodes, 1986;Smith, Grabowecky, & Suzuki, 2008) in explicit tasks requiring face recognition, judgments of orientation and judgments of ''likeliness'' of mirror reversed versus normally oriented faces. These studies, however, remained at the explicit level and only studied a limited number of trials.…”
